Filed: 1991-12-17
Abstract: PURPOSE:To prevent collapse from occurring by transmitting laser beams toward the other port from one port along the left and right sides of a tunnel kiln, receiving laser beams and detecting the tilt fall of saggar by the interruption of laser beams. CONSTITUTION:Laser transmitters 12 emitting laser beams 14 along the sidewalls of a tunnel kiln 6 and laser receivers 13 receiving laser beams are installed onto both sidewalls, and connected to the laser transmitters 15 and laser receivers 16 of laser converters 17. When saggar 10 is moved by a saggar truck 5, laser beams 14 are set so as to be interrupted when saggar 10 is tilted. Consequently, when saggar 10 is inclined, the laser receivers 13 do not receive beams, and the laser receivers 16 output tilt fall detecting signals 18 to an alarm panel 19. The alarm panel 19 gives an alarm while outputting an interlock signal 21, thus stopping a saggar truck driving panel 20. It is preferable that the arrangement of the transmitters 12 and the receivers 13 is reversed left and right.

Title: Polymer dispersion type liquid crystal display device
Inventor: OGAWA TETSU
IPC: G09F9/35
Filed: 1989-12-22
Abstract: PURPOSE:To improve the contrast of a polymer dispersion type liquid crystal device (PD-LCD) and to expand the color reproduction range by incorporating dichroic pigment in a liquid crystal compound or mixture layer. CONSTITUTION:Liquid crystal is dispersed normally as small particles in the PD-LCD and liquid crystal molecules and the dichroic pigment are oriented at random. Respective materials are so selected that the dielectric anisotropy DELTAepsilonof the liquid crystal is positive and the refractive index to ordinary light is nearly equal to that of a polymer. When no voltage is applied, the light absorption of the dichroic pigment is added and the light transmissivity in a dark state is reducible. When a voltage is applied, on the other hand, the liquid crystal molecules are oriented in the direction of an electric field, but the dielectric pigment is also oriented in the electric field direction associatively with the motion of the liquid crystal molecules. At this time, the plane of polarization of incident light is put in orthogonal relation with the axis of light absorption of the dichroic pigment, so no light absorption is generated in principle and the incident light travels straight as it is.

Title: Afterglow type display
Inventor: TAKANO YASUSHI
IPC: G09F13/22
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To make it possible to change display contents under an environment where the emitted light of phosphors is visible and an environment where the emitted light is invisible by forming the surfaces of the light emitting parts and non-light emitting parts including the adjacent phosphors to the same colors as each other in regions inclusive of the parts in contact with their boundaries. SOLUTION: A display 2 of a circle mark and a display 3 of a cross mark exist on the front surface of, for example, a sheet-like display 1. The parts 4 forming the display of the circle mark and the parts 5 overlapping the display of the cross mark are formed as the light emitting parts contg. the phosphors. The parts 6 constituting the display 3 the cross mark and the parts 5 overlapping on the display of the circle mark are colored to, for example, black and the other parts are colored to, for example, gold. Then, the display of the circle mark is recognizable under the environment where the emitted light of the phosphors is visible, for example, in a dark place. On the other hand, the black display of the cross mark is recognizable on the golden ground under, for example, natural light.  The light emitting parts are selectively coated to the same colors by the gold of the ground color or the black of the display of the cross mark and therefore, the presence of the display of the circle mark is not recognizable.

Title: Offset correcting apparatus
Inventor: OKAMOTO KENJI
IPC: G01C21/08
Filed: 1989-12-21
Abstract: PURPOSE:To make it possible to estimate the present bearing of a moving body accurately by evaluating the offset of the output data of a turning angular- speed sensor by using a specified expression, and correcting the offset value. CONSTITUTION:An offset value omega of a turning angular-speed sensor 41 is obtained from an actually measured output value V of the sensor 41 when a moving body is stopped and a past offset value omega' by using an expression omega=(1-K(T))omega' + K(T)V (where K(T) is weighting coefficient which is changed in correspondence with a period T from the obtained time of the past offset value omega' to the actually measured time of the output value V of the sensor 41). Then, the offset value omega which is obtained with an offset computing means is used to correct the offset value of a gyroscope 43 (turning angular-speed sensor). Thus, the accurate bearing of the moving body reflecting the actual offset characteristic of a turning angular-speed sensor can be estimated. The position of the moving body in movement can be obtained accurately from this bearing.

Title: Flexible tube motor
Inventor: HOSOKAWA KATSUO
IPC: F04B43/12
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To enhance the efficiency of a motor and improve its service life by expanding a tube by a mixed pressure fluid fed from a mixed fluid feeding means to feed the mixed pressure fluid mixed with a lubricant, and pushing to turn a roller by expansion of the tube to rotate a rotor. SOLUTION: When hot water is fed to an evaporator, evaporated liquid such as liquid pentane in the evaporator is evaporated to become pentane gas PG, and this pentane gas PG is mixed with lubricating oil separately fed by an oil pump and fed in the mixed state to a feed port 3 of a tube motor through a gas pipe 28. This pentane gas PG is fed to a first chamber (a) of a tube 4, but since the first chamber (a) is in a sealed state by a roller 7 energized by a pre-load spring 12, the first chamber (a) is expanded by the feeding of the pentane gas so as to push a roller 7 to turn in a forward direction R along with other rollers 8-10 by the expansion force. A rotor 16 is therefore rotated clockwise.

IPC: B65D81/02
Filed: 1994-12-16
Abstract: PURPOSE: To provide a packaging material which uses less materials, is lightweight, provides satisfactory ventilation, and exhibits excellent cushioning performance, especially to strong impact, compared to hammock packing using a conventional film, by putting a cushion onto the bottom of a box opposite a film, and by stretching the film without covering the entire opening so that air freely moves inside and outside the film. CONSTITUTION: Boxes 11 and 12 take the form of a C type, and to the face of the box 11, usually called the cover of the C type box, opposite its opening, a cushion 16 is stuck. Also across the opening of the box 12, usually serving as the bottom of the C type box, a film 14 is stretched. An item 15 to be packed is placed on the cushion 16 of the box 11, the box 12 is inserted into the box 11 from above and, with the boxes pressed to each other, a sleeve 13 is then fitted on them. Because the boxes 11 and 12 are fixed from outside by the sleeve 13, the item 15 is pressed by the restoring force of the film 14 stretched over the cushion 16, and is so fixed in position by the film 14 as to be prevented from being displaced in the pack. This makes it possible to reduce the amount of the cushion 16 to the smallest amount necessary.

Abstract: PURPOSE:To allow suction force to change proper suction force by providing two variable resistors different in maximum resistance values and arbitrarily selecting the variable resistance by means of a changeover switch. CONSTITUTION:When the strokes of a first variable resistor 8 and a second variable resistor 9 are (a) and a switch 7 is connected to the first variable resistor 8 side, a current flowing to current limit resistor 10   the first variable resistor 8   switch 7   resistor 6 is charged in a capacitor 5, and when the charged voltage reaches the ON-voltage of a trigger element 4, a trigger pulse is generated, a bidirectional thyristor 4 is turned on, a motor 2 is rotated, and a power at such a time is made into (b). Next, when the switch 7 is changed over to the second resistor 9 side, since the current flows through the second resistor 9, the resistance value of the second resistor 9 is smaller than the resistance value of the first resistor 8, and thereby, the power rises up to (c). In such a manner, by setting the rising value of the power with the changeover of the switch 7 according to the point of each stroke, the proper up-and-down of the input according to each cleaning surface can be executed only by the changeover of the switch 7.
